NEURONAL ACTIVITY IN THE BRAIN CHANGES DURING EXERCISE IN ATTENTION STATES, WARM-UP, SUBMAXIMAL EFFORT, AND RECOVERY, AFTER NEUROFEEDBACK-EEG TRAINING IN MOTION

The aim of the study was to show changes in EEG during exercise in attention states A, warm-up W, submaximal effort E, and recovery states R, during Neurofeedback-EEG training. Examined 10 track and field athletes and 10 swimmers based on EEG measurements during physical exercise. The track and field athletes underwent 20 Neurofeedback-EEG training sessions on the elliptic ergometer and swimmers on the swimming ergometer, with speed measurement. All the measurements were performed twice: before and after Neurofeedback-EEG training. Participation in Neurofeedback-EEG training combined with physical exercise change brain activity and result in a substantial modulation of the spectral amplitude within the sources located near the frontal lobe, sensory cortex, motor cortex, and anterior parietal and occipital lobes. However, depending on the movement speed, the differences in EEG are statistically insignificant in many points of the skull, on the frontal, parietal, temporal, and occipital lobes. Participation in Neurofeedback-EEG training result in a substantial modulation of the spectral amplitude within the sources located near the frontal lobe, sensory cortex, motor cortex, and anterior parietal and occipital lobes. The changes are related to the movement speed and the points of the skull related to the activity of specific brain areas.
